Peracarida (e.g. woodlice and side-swimmers) are, together with their sister-group Eucarida krill decapods), the most speciose group of modern crustaceans, suggested to have appeared as early Ordovician. While eucarids' incursion onto land consists mainly freshwater littoral grounds, some peracarids evolved fully terrestrial ground-crawling ecologies, inhabiting even our gardens in temperate re...

The ammonoids of the suborder Tornoceratina from Middle to Late Devonian Red Ironstone Formation area around Dillenburg (eastern Rhenish Mountains) are revised, mainly based on historical collections stored in Museum für Naturkunde, Berlin. species Tornoceras typus (Sandberger & Sandberger, 1851), frechi Wedekind, 1918 and Epitornoceras mithracoides (Frech, 1888) re-described original mater...

New observations on the axial skeleton of the extant lungfish Neoceratodus forsteri (Dipnoi; Sarcopterygii) indicate that neural and haemal arch elements develop more independently than previously believed. For example, while the cartilaginous neural arches/spines begin development anteriorly, just behind the skull, the distal supraneurals first form separately in the posterior region of the ax...

Gondwanan floras of Late Devonian age are poorly known. In Australia, the rare studies that have been published on plants old and need reinvestigation. This paper is an account plant macro- micro-remains found in Mandowa Mudstone at Barraba, New South Wales. According to miospores, late latest Famennian age. The record anatomically preserved specimens diversified, with nine taxa assigned Lycops...

An abrupt transition in the fossil record separates Early Devonian euphyllophytes with a simple structure from broad diversity of structurally complex Middle–Late plants. Morphological evolution and phylogeny across this are poorly understood due to incomplete sampling record. We document new radiatopsid integrate it analyses addressing euphyllophyte relationships. Anatomically preserved Emsian...

The Massif Central, like the southern part of the Massif Armoricain, belongs to the North Gondwana margin. The Massif Central consists of a stack of nappes resulting of six main tectonicmetamorphic events. The first one, D0, is coeval with an Early Late Silurian (ca 415 Ma) highpressure (or ultra high-pressure) metamorphism for which the associated structures are poorly documented. The Early De...
